A CORPORATION OF LOOSE LEAF BINDER.

Specification of Letters Patent.-

Iatented Apr. 8, 1919.

Application filed May 27, 1915. Serial 110.30,?95.

To all whom it may concern Be it known that I, WILLIAM H. EDwARDs, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented new and useful Improvements in Loose-Leaf Binders, of which the following is a specification.

The present invention relates to loose leaf binders; and its object is generally, to provide an improved device of that character; and more particularly, to provide an improved protecting shield for the leaf-holding members of such devices; and further, to provide an improvedconstruction of, and

' connection between, the covers and the back of such devices; and further, to provide an improved attachment to the covers of the parts by which the leaf-holding members are carried on the covers of such devices.

These and any other objects appearing hereinafter are attained by, and the invention finds preferable embodiment in, the structures hereinafter described and illustrated by the accompanying drawings, in which Figure 1 is a plan View of the inside of the opened covers of a loose-leaf binder con taining leaves;

Fig. 2 is a transverse sectional view of the same; and

Fig. 3 is an enlarged sectional view of parts taken on line 33 of Fig. 1.

Fig. 4k is a sectional view showing the central portion of Fig. 2 on an enlarged scale.

In the embodiment of the invention chosen for illustration by the drawings and detailed description in the body of this specification, the covers 1 and 2 are connected to the back 3 by link portions 4 flexibly hinged to the back at 5 and to the respective covers at 6.

Flexible leaf-holding members carrying the leaves 7 extend from cover to cover. Said members are preferably resilient, as the steel springs 8. These springs are attached to cover 1 as by rivets 9 and the clips 10 carried by the covers rigid plate 11; and they are adjustably attached to cover 2 as by the guide clips 12 (carried by this covers rigid plate 18) in which clips said members are slidable, and they are attached at their right-hand ends to a cross bar 14, by which such members may be drawn outwardly by hand to a proper adjusted position, the ends of the cross bar 15 so as to bring 1ts eccentric cams 16 into,

clamping engagement with said members.

A covering material .or binding 17 extends integrally over and outside the covers, the links andrthe back 3, being secured thereto as by gluing; through the covers, the covering material and the rigid plates serve to securely fasten these plates to the respectivecovers.

. Aflexible shield 19 is adapted to protect each leaf-holding member in its adjusting movement through the guide clip 12 and in its flexing movement in such clip and in the leaf body. This shield lies adjacent to the leaf-holding member and flexes therewith: one end of this shield 19 is fixed relatively to the member 8 as by the rivet 9: it has a certain longitudinal movement relatively to said member and independent of such members adjusting movement. It thus takes no part in holding or adjusting the covers relatively to each other, for its right-hand end (as particularly shown in Fig. 3) is slotted at 20 for the free sliding engagement of the pin 21 therein, by which pin the leaf-holding member is secured to the clip 22 on the cross bar. A suitable separating piece, as the cam shaft, serves to hold said member and its shield apart for a portion of their length along the cover, as shown in Fig. 3.

The invention being intended to be defined solely by the claims, is not to be limited by details of construction shown or described.

I claim:

1. In a device of the character described; a pair of covers; a flexible leaf-holding member connecting the covers; adjusting means for said member carried by one cover; and a flexible shield adjacent said member and flexing therewith and having a longitudinal movement relatively to sai member and independent of its adjusting movement, and adapted to protect said member in its adjusting and flexing movements.

2. In a device of the character described; a pair of covers; an adjustable flexible leafholding member connecting the covers; and a flexible shield adjacent said member and flexing therewith and having a longitudlnal movement relatively to said member and 1ndependent of its adjusting movement, and

adapted to protect said member in its adjusting and flexing movements, and a separating piece adapted to hold'said member and its shield apart for a portion of their length along said cover. 3. In a device of the character described; a back; a pair of covers; a pair of links, one between the back and One cover and the other between the back and the other cover; and connections between the back and the links and between the links and the covers; which connections are more flexible than the back or the links or the covers.

4. In a device of the character described; a back; a pair of covers hinged thereto; a covering material extending integrally over and outside the covers and the back; a flexible leaf-holding member extending from cover to cover; rigid plates on the inside of the covers respectively; means for attaching said members to the plates; and rivets extending through the covers, the covering material and the plates to fasten the plates to the respective covers.

- 5. In a device of the character described; a pair of covers; a covering material extending integrally over and outside the covers; a flexible leaf-holding member extending from cover to cover; rigid plates on the inside of the covers respectively; means for attaching said member to the plates; and rivets extending through the covers, the covering material and the plates to fasten the plates to the respective covers.

In testimony whereof I have hereunto set my hand in presence of subscribing witnesses.
